Overview

Package speech provides access to the Cloud Speech API.

This package is DEPRECATED. Use package cloud.google.com/go/speech/apiv1 instead.

For product documentation, see: https://cloud.google.com/speech-to-text/docs/quickstart-protocol

Creating a client

Usage example:

import "google.golang.org/api/speech/v1beta1"
...
ctx := context.Background()
speechService, err := speech.NewService(ctx)

In this example, Google Application Default Credentials are used for authentication.

For information on how to create and obtain Application Default Credentials, see https://developers.google.com/identity/protocols/application-default-credentials.

Other authentication options

To use an API key for authentication (note: some APIs do not support API keys), use option.WithAPIKey:

speechService, err := speech.NewService(ctx, option.WithAPIKey("AIza..."))

To use an OAuth token (e.g., a user token obtained via a three-legged OAuth flow), use option.WithTokenSource:

config := &oauth2.Config{...}
// ...
token, err := config.Exchange(ctx, ...)
speechService, err := speech.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))

See https://godoc.org/google.golang.org/api/option/ for details on options.

                  func (c *OperationsGetCall) IfNoneMatch(entityTag string) *OperationsGetCall

                    IfNoneMatch sets the optional parameter which makes the operation fail if the object's ETag matches the given value. This is useful for getting updates only after the object has changed since the last request. Use googleapi.IsNotModified to check whether the response error from Do is the result of In-None-Match.

                    type OperationsListCall

                    type OperationsListCall struct {
                    	// contains filtered or unexported fields

                          func (*OperationsListCall) Filter

                          func (c *OperationsListCall) Filter(filter string) *OperationsListCall

                            Filter sets the optional parameter "filter": The standard list filter.

                            func (*OperationsListCall) Header

                            func (c *OperationsListCall) Header() http.Header

                              Header returns an http.Header that can be modified by the caller to add HTTP headers to the request.

                              func (*OperationsListCall) IfNoneMatch

                              func (c *OperationsListCall) IfNoneMatch(entityTag string) *OperationsListCall

                                IfNoneMatch sets the optional parameter which makes the operation fail if the object's ETag matches the given value. This is useful for getting updates only after the object has changed since the last request. Use googleapi.IsNotModified to check whether the response error from Do is the result of In-None-Match.

                                func (*OperationsListCall) Name

                                  Name sets the optional parameter "name": The name of the operation's parent resource.

                                  func (*OperationsListCall) PageSize

                                  func (c *OperationsListCall) PageSize(pageSize int64) *OperationsListCall

                                    PageSize sets the optional parameter "pageSize": The standard list page size.

                                    func (*OperationsListCall) PageToken

                                    func (c *OperationsListCall) PageToken(pageToken string) *OperationsListCall

                                      PageToken sets the optional parameter "pageToken": The standard list page token.

                                      func (*OperationsListCall) Pages

                                        Pages invokes f for each page of results. A non-nil error returned from f will halt the iteration. The provided context supersedes any context provided to the Context method.

                                        type OperationsService

                                        type OperationsService struct {
                                        	// contains filtered or unexported fields
                                        }

                                        func NewOperationsService

                                        func NewOperationsService(s *Service) *OperationsService

                                        func (*OperationsService) Get

                                          Get: Gets the latest state of a long-running operation. Clients can use this method to poll the operation result at intervals as recommended by the API service.

                                          func (*OperationsService) List

                                            List: Lists operations that match the specified filter in the request. If the server doesn't support this method, it returns `UNIMPLEMENTED`.

                                            NOTE: the `name` binding allows API services to override the binding to use different resource name schemes, such as `users/*/operations`. To override the binding, API services can add a binding such as "/v1/{name=users/*}/operations" to their service configuration. For backwards compatibility, the default name includes the operations collection id, however overriding users must ensure the name binding is the parent resource, without the operations collection id.

It is used by [gRPC](https://github.com/grpc). The error model is designed to be:

                                                                                - Simple to use and understand for most users - Flexible enough to meet unexpected needs

                                                                                # Overview

                                                                                The `Status` message contains three pieces of data: error code, error message, and error details. The error code should be an enum value of google.rpc.Code, but it may accept additional error codes if needed. The error message should be a developer-facing English message that helps developers *understand* and *resolve* the error. If a localized user-facing error message is needed, put the localized message in the error details or localize it in the client. The optional error details may contain arbitrary information about the error. There is a predefined set of error detail types in the package `google.rpc` that can be used for common error conditions.

                                                                                # Language mapping

                                                                                The `Status` message is the logical representation of the error model, but it is not necessarily the actual wire format. When the `Status` message is exposed in different client libraries and different wire protocols, it can be mapped differently. For example, it will likely be mapped to some exceptions in Java, but more likely mapped to some error codes in C.

                                                                                # Other uses

                                                                                Example uses of this error model include:
